Among the estimated 100 billion solar systems in the known universe, evolving life is surely abundant. That evolution is a process of "becoming" in each case. Since Newton, we have turned to physics to assess reality. But physics alone cannot tell us where we came from, how we arrived, and why our world has evolved past the point of unicellular organisms to an extremely complex biosphere.

Stepping effortlessly from myth to cutting-edge science, Mutants gives a brilliant narrative account of our genetic code and the captivating people whose bodies have revealed it - a French convent girl who found herself changing sex at puberty; children who, echoing Homer's Cyclops, are born with a single eye in the middle of their foreheads; a village of long-lived Croatian dwarves; one family, whose bodies were entirely covered with hair, was kept at the Burmese royal court for four generations and gave Darwin one of his keenest insights into heredity.

Welcome everyone to your guide to Human Anatomy & Physiology 2!

I have been teaching college level human anatomy and physiology for many years, as well as other courses. My other classes taught have included: pathophysiology, biology, zoology, microbiology, and others. In this time I have seen thousands of students. I have learned through the years the best ways to learn the most ...

The desire for dignity is universal and powerful. It is a motivating force behind all human interaction - in families, in communities, in the business world, and in relationships at the international level. When dignity is violated, the response is likely to involve aggression, even violence, hatred, and vengeance. On the other hand, when people treat one another with dignity, they become more connected and are able to create more meaningful relationships.

Spectacular fossil finds make today's headlines; new technology unlocks secrets of skeletons unearthed 100 years ago. Still, evolution is often poorly represented by the media and misunderstood by the public. A potent antidote to pseudoscience, Written in Stone is an engrossing history of evolutionary discovery for anyone who has marveled at the variety and richness of life.

There's a silent epidemic in Western civilization, and it is right under our noses. Our jaws are getting smaller and our teeth crooked and crowded, creating not only aesthetic challenges but also difficulties with breathing. Sandra Kahn and Paul R. Ehrlich, a pioneering orthodontist and a world-renowned evolutionist, respectively, present the biological, dietary, and cultural changes that have driven us toward this major health challenge. They propose simple adjustments that can alleviate this developing crisis.

A riveting investigation of the myriad ways that parasites control how other creatures - including humans - think, feel, and act. These tiny organisms can live only inside another animal, and, as McAuliffe reveals, they have many evolutionary motives for manipulating their host's behavior. Far more often than appreciated, these puppeteers orchestrate the interplay between predator and prey.

We have always identified trends as bad (loosening of the moral fiber) or good (better ethnic eating in urban areas). But Stephen Jay Gould argues that this mode of interpretation is a bias that needs correcting. In Full House, Gould presents the truth about progress, evolution, and excellence, as well as a different way to understand trends other than as entities moving in a definite direction.

The problem of agriculture is as old as civilization. Throughout history, great societies that abused their land withered into poverty or disappeared entirely. Now we risk repeating this ancient story on a global scale due to ongoing soil degradation, a changing climate, and a rising population. But there is reason for hope. David R. Montgomery introduces us to farmers around the world at the heart of a brewing soil health revolution that could bring humanity's ailing soil back to life remarkably fast.

Analyzing brainwaves, the imperceptible waves of electricity surging across your scalp, has been possible for nearly a century. But only now are neuroscientists becoming aware of the wealth of information brainwaves hold about a person’s life, thoughts, and future health. From the moment a reclusive German doctor discovered waves of electricity radiating from the heads of his patients in the 1920s, brainwaves have sparked astonishment and intrigue, yet the significance of the discovery and its momentous implications have been poorly understood.

On the Alaska Peninsula, where exceptional landscapes are commonplace, a small river attracts attention far beyond its scale. Each year, from summer to early fall, brown bears and salmon gather at Brooks River to create one of North America's greatest wildlife spectacles. As the salmon leap from the cascade, dozens of bears are there to catch them, and thousands of people come to watch in person or on the National Park Service's popular Brooks Falls Bearcam. The Bears of Brooks Falls tells the story of this region and the bears that made it famous.

The Story of the Earth in 25 Rocks tells the fascinating stories behind the discoveries that shook the foundations of geology. In 25 chapters, Donald R. Prothero recounts the scientific detective work that shaped our understanding of geology, from the unearthing of exemplary specimens to tectonic shifts in how we view the inner workings of our planet.

Wild Life follows Rae on her adventures and explorations in some of the world’s most remote locales. Hers is a story about a nearly twenty-year career in the wild—carving a niche as one of very few Black female scientists—and the challenges she had to overcome, expectations she had to leave behind, and the many lessons she learned along the way.

For all of neuroscience's advances, we've made little progress on its biggest question: How do simple cells in the brain create intelligence? Jeff Hawkins and his team discovered that the brain uses map-like structures to build a model of the world - not just one model, but hundreds of thousands of models of everything we know. This discovery allows Hawkins to answer important questions about how we perceive the world, why we have a sense of self, and the origin of high-level thought.

Dr. Catherine Kleier invites us to open our eyes to the phenomenal world of plant life and to the process she calls “Natura Revelata”, the joy of celebrating and learning from the secrets of nature. As Dr. Kleier shares her knowledge with contagious excitement for her subject, she emphasizes the middle ground: Instead of focusing on cell microbiology or the study of ecosystems and habitats, she stresses the basic biology, function, and the amazing adaptations of the plants we see all around us.

Insects walk on water, snakes slither, and fish swim. Animals move with astounding grace, speed, and versatility: how do they do it, and what can we learn from them? In How to Walk on Water and Climb up Walls, David Hu takes listeners on an accessible, wondrous journey into the world of animal motion. From basement labs at MIT to the rain forests of Panama, Hu shows how animals have adapted and evolved to traverse their environments, taking advantage of physical laws with results that are startling and ingenious.

Where did I come from? Why do I have two arms but just one head? How is my left leg the same size as my right one? Why are the fingerprints of identical twins not identical? How did my brain learn to learn? Why must I die? Questions like these remain biology's deepest and most ancient challenges. They force us to confront a fundamental biological problem: How can something as large and complex as a human body organize itself from the simplicity of a fertilized egg?

In recent years, the advent of MRI technology seems to have unlocked the secrets of the human mind, revealing the sources of our deepest desires, intentions, and fears. As renowned psychiatrist and scholar Sally Satel and psychologist Scott O. Lilienfeld demonstrate in Brainwashed, however, the explanatory power of brain scans in particular and neuroscience more generally has been vastly overestimated.

Every year on January 1, a quirky crowd of adventurers storms out across North America for a spectacularly competitive event called a Big Year: a grand, grueling, expensive, and occasionally vicious, "extreme" 365-day marathon of birdwatching. For three men in particular, 1998 would be a whirlwind, a winner-takes-nothing battle for a new North American birding record.
